Cipher Core Strategy: Solve Any Word in Four Guesses

Cipher Core is the heart of Cipher Siege: a hidden word, six guesses, and colour-coded feedback after each try. It looks like luck, but strong players solve almost every puzzle in four guesses by following a simple method. Here it is.

Reading the feedback

• Cyan: right letter, right spot. Keep it there.
• Purple: the letter is in the word, but not in that spot. Move it.
• Grey: the letter is not in the word (or not an extra copy of it). Stop using it.

A subtle rule: if you guess a word with two copies of a letter and only one lights up, the word contains exactly one. Grey on the second copy means “no more of these”, not “none at all”.

Step 1: Open with a tested word

Don’t improvise your first guess. Use a word that splits the answer list well. Our data says TARES for 5 letters and SALTER for 6; see the full list of best starting words for every length.

Step 2: Explore, don’t exploit (yet)

The most common mistake is trying to guess the answer on turn two. If your opener found one purple letter, there are still dozens of possible words. A second guess that uses five fresh common letters (for example N, O, I, D, C) will usually tell you more than a guess that merely shuffles the one letter you already know.

A good rule: keep exploring until you can write down the remaining candidates on one hand. Then switch to guessing them.

Step 3: Use position, not just presence

A purple letter tells you two things: it’s in the word, and it’s not here. Each purple narrows the letter to fewer positions. With two or three purples you can often work out exact positions before you guess. For example, if S was purple in position 1 and position 3, and position 5 is the most common home for S (it is in 32.9% of 5-letter answers), the S almost certainly goes last.

Step 4: Watch for word families

Some puzzles are traps: you know four of five letters and there are still six answers, like _IGHT (fight, light, might, night, right, sight, tight). Guessing them one by one can burn all your guesses. Instead, play a word that contains several of the missing first letters at once, such as one using F, L, M and N. One “wasted” guess eliminates most of the family, and you win on the next.

Step 5: Remember repeated letters

If your candidates are running out and nothing fits, consider a doubled letter. Repeats get far more common as words get longer: 33% of 5-letter answers and 66.9% of 7-letter answers have one.

Playing the timer

Arcade puzzles are untimed, so they are the place to practise the method. In Castle Sieges, every tier above Page has a time limit per word: 60 seconds at Squire, 90 at Knight, 120 at Paladin, 180 at King and 240 at Emperor. On the clock, a decent guess now beats a perfect guess too late. A War Horn boost adds 30 seconds when you’re close.

Common mistakes

• Reusing grey letters. Every grey letter you type again is a wasted slot. Check the keyboard before each guess.
• Keeping a purple letter in the same spot. Purple means “not here”. Move it every time.
• Guessing rare words. Answers are drawn from graded word lists, so common words are far more likely than obscure ones at lower tiers.
• Forgetting the end of the word. S, D and E are the most common final letters. If the last slot is empty late in a puzzle, start there.

How rewards scale

In the Arcade, each tier has an entry fee and pays out on a win:

Because a win pays roughly double the entry fee, you only need to win about half your games to profit. If your win rate at a tier drops below that, step down a tier, sharpen the method, and climb back up.
